The quality products of ALAS Klöch are CE-certified according to the corresponding harmonized EN standards. The company’s own laboratory ensures the sustainable supply of high-quality aggregates for a wide range of applications in the construction industry within the framework of the company’s own quality control.

Aggregates for asphalt and road concrete represent the most important product group. Due to the excellent quality of the source rocks (basalt and diabase), the highest requirements for strength, skid resistance and ASR resistance are met.

Another very important product group is aggregates for hydraulically bound and unbound base courses. The production from high-quality rock with one hundred percent fracture content ensures maximum stability and sustainable stability of paved roads and surfaces.
